Abstract:
Objective To explore the characteristics of calcifying pseudoneoplasm of the neuraxis ( CAPNON) , and to improve the di-agnostic level and standard of treatment. Methods The clinical traits, imaging features and curative effect of one case of CAPNON who were treated in our departmen were analyzed combined with the pathological analysis and literature review. Results Transient back pain was the only clinical presentation of the patient. CT images showed obvious calcification. MRI showed low signal in T1-weigthed images and T2-weighted images. Examined with the contrast-enhanced MR images, the lesion showed inhomogeneous enhancement. No nervous symptom newly occurred in the 6-month follow-up. Conclusion Symptoms of patients with CAPNON are generally related to local compression or irri-tation of the adjacent tissue. CAPNON should be highly suspected in patients with dense calcification in the CT combined with low signal in T1-weigthed images and T2-weighted images and rim or internal inhomogeneous linear enhancement in the MRI. The final diagnosis depends on the histopathological analysis, and surgical resection is the major therapy.
